I just painted a room with the first coat 3 weeks ago and the second coat today. I don’t like the color. How long do I have to wait to repaint with a new color. Going to go from a light blue to Navajo White. Also I am expecting my rug to be removed and hardwood floors to be placed in within a week. Should I paint now or wait until I am just on plywood or when the floors are done? Do I need to clean the wall and/or sand for the next paint color and if I choose to do so if my rug is removed? Thank you.
